(27) A plan view of the overall apparatus is shown in
(28) The movement of the sliding section 106 is driven by a potential energy source. In some embodiments a cable 108, a pulley 110 and a weight 112. Collectively, these items are assembled to exert an opening force on the sliding section 106. Generally, under the influence of gravity the weight will descend and exert a force on the cable 108. The pulley 110 translates the vertical force of the descending weight into a horizontal force and pulls the sliding section 106 open. Under the influence of the weight, the sliding section's 106 default position is open, and energy must be exerted to close the sliding section 106. In alternative embodiments the potential source may comprise electrical energy such as a battery or power from the grid may be used to activate and actuate the subsection.
(29) As shown in
(30) The ladder system also utilizes a weight 122, a cable 124 and a pulley 126 to cause an interaction with the sliding section of the grate 106. Generally, under the influence of gravity the weight 122 will descend and exert a force on the cable 124. The pulley 126 translates the downward vertical force of the descending weight into an upward vertical force and pulls the sliding section of the ladder 114 upward. Under the influence of the weight 122, the ladder sliding section's 114 default position is up which creates contact with the sliding section of the grate 106.
(31) However, when an individual exerts weight on or near the sliding section of the ladder 114, the force exceeds the force of the weight 122 holding the ladder up and the ladder section 114 slides downward on the ladder frame 116. As the ladder section 114 moves downward, the catch pegs 120 lose contact with the sliding section of the grate 106. Without the pegs to restrict the movement of the sliding section of the grate 106, the weight drops 112 and the sliding section of the grate 106 opens.
(32) The ladder system is not attached to the main grate so larger individuals may simply remove the entire main grate 102, and use the ladder 114 to exit the well.
(33) In one embodiment, the ladder system further comprises one or more members to provide stability and maintain the ladder system in an upright position. These members are depicted in conjunction with the ladder system in
(34) In another embodiment, the apparatus utilizes springs to apply the requisite forces. A plan view of the overall apparatus is shown in
(35) The movement of the sliding section 306 is driven by one or more mechanical springs 308. Collectively, these springs are assembled to exert an opening force on the sliding section 306. Generally, under the influence of the springs 308 the sliding section's 306 default position is open and energy must be exerted to close the sliding section 306. The springs may apply a tension, compression, or torsion force to open the sliding section of the grate 306.
(36) As shown in
(37) The ladder system utilizes one of more springs 318 to cause interaction with the sliding section of the grate 306. Generally, under the influence of the springs 318, the ladder sliding section's 310 default position is up which creates contact with the sliding section of the grate 306.
(38) However, when an individual exerts weight on or near the sliding section of the ladder 310. The force exceeds the force of the springs 318 forcing the ladder section 310 up and the ladder sections 310 slides downward on the ladder frame 312. As the ladder section 310 moves downward, the catch pegs 316 lose contact with the sliding section of the grate 306. Without the pegs 316 to restrict the movement of the sliding section of the grate 306, the springs 308 cause the sliding section of the grate 306 to open.
(39) The ladder system is not attached to the main grate so larger individuals may simply remove the entire main grate 302, and use the ladder 310 to exit the well.
(40) In one embodiment, the ladder system further comprises one or more members to provide stability and maintain the ladder system in an upright position. These members are depicted in conjunction with the ladder system in

(42) Referring now to
(43) In some embodiments the egress apparatus comprises a first position wherein the sliding section 604 ladder is in a raised position the top of the sliding section blocking the movable section from moving, thus the main grate 606 is in a closed position.
(44) In some embodiments the egress apparatus comprises a second position wherein the sliding section is in a lowered position, the top of the sliding section not blocking the movable section from moving, thus the movable subsection 608 of the main grate 606 can be moved to an open position.
(45) In some embodiments a trigger may be used to control when the sliding section 604 moves from its raised position to its lower position. In some embodiments the trigger may be any trigger known in the art. In some embodiments the trigger may be a notch and tongue trigger which releases upon being moved. In some embodiments the trigger may be a friction trigger wherein the structure of the sliding mechanism 604 is too tight to freely slide past the stationary section 602 without additional force. In some embodiments the trigger mechanism may be a spring. In some embodiments the trigger mechanism may have a trigger which is actuated when it is squeezed.
(46) In some embodiments the sliding section 604 is held in the raised position by a trigger comprising a cantilever weight plate 616 that is hingedly coupled on a first end to the sliding section 604 and the weight is suspended on a second end; the plate freely pivots on the fulcrum 618. In a first raised position the force created by the weight of the cantilever is greater than the force created by the weight of the sliding section 604 ladder. At the top of the sliding section 604 are catch members 610 which secure a moveable section 608 of the main grate in a closed position. Thus in some embodiments the first position may comprise the sliding section 604 in a raised position restraining movement of the moveable section 608.
(47) In some embodiments there is a second position. This occurs as additional force is added to the force of the sliding section so that the downward force on the sliding section is greater than the force created by the weight on the cantilever. This additional weight causes the sliding section 604 to a lowered position, the cantilever to pivot on the fulcrum 618, raising the weight and lowering the sliding section. In some embodiments the sliding section in the lowered position moves the catch elements 610 away from the moveable section 608 of the main grate 606, freeing the moveable section 608 to move from a closed position to an open position. The movement of the moveable section 608 from the closed position may be automatic (by a bias force such as springs, weights etc) or it may be manual. Thus in some embodiments the second position may comprise the sliding section 604 in a lowered position and the moveable section 608 unrestrained and capable of being moved to an open position.
(48) In some embodiments, the window well egress apparatus 600 may include one or more features of the window egress well apparatuses of any of the
(49) In some embodiments, the main grate 606 may include a moveable subsection 608 that may move between an open and closed position. In some embodiments, the sliding section 604 may include one or more slide brackets 607, which may each include a channel 613 through which the stationary section 602 extends. Brackets 607 aligns the sliding section 604 and stationary section 602 during the sliding section's 604 actuation from the raised position to the lower position. As a result, slide brackets 607 may be positioned on either the stationary section 602 or the sliding section 604.
(50) In some embodiments, an upper end of the sliding section 604 may include one or more catch elements 610, which may selectively secure the moveable subsection 608 in the closed position when the sliding section 604 is in the raised position. In some embodiments, the catch elements 610 may include pins, pegs, protrusions, clips, or other suitable elements which physically obstruct or block the moveable subsection's 608 movement. In some embodiments, in response to the actuation of the sliding section 604 sliding from the raised position to the lowered position, by, for example, a person actuating the sliding section 604 by stepping on or applying a downward force to the sliding section 604, the catch elements 610 may move below the moveable subsection 608, which may stop blocking the movable subsection 608 and allow it to move to the open position. When the moveable subsection 608 is in the open position, the person may exit the window well structure through an opening 609 in the main grate 606.
(51) In some embodiments, the catch elements 610 may selectively secure the moveable subsection 608 in the closed position. In some embodiments, the moveable subsection 608 may automatically move to the open position in response to removal of the catch elements 610 from the path of the moveable subsection 608. In some embodiments, this automatic movement of the movable subsection 608 may be due to one or more springs, one or more weights, and/or another suitable mechanism that moves the moveable subsection 608 to the open position. In some embodiments, a mechanical system may include a cable, pulley, and weight, which may work collectively to apply an opening force on the moveable subsection 608 in response to movement of the catch elements 610 below the moveable subsection 608.
(52) Alternatively the moveable subsection may be actuated by the user. In this embodiment the user may remove the catch elements 610 from the path of the movable subsection 608 by actuating the sliding section 604 and then manually slide the moveable subsection 610 to its open position.

Alternatively, in some embodiments the stationary section's 602 coupling member may be coupled or selectively couple directly to the main grate 608. In some embodiments, the frame 602 may rest on the ground at the bottom of the window well. In some embodiments the frame may hang from a support, such as the top lip of the window well or the main grate. In some embodiments the frame 602 may lean at an angle or in some embodiments the frame 602 may hang substantially vertically.
(59) In some embodiments the rails 622 of the main ladder support frame are substantially parallel and may be flat or round, the cross-sectional shape of the rails 622 are selected to nest within the sliding brackets 607 or channels 613. The bottom of the main latter support frame stationary section 602 The frame 602 comprises two parallel support rails which designed to be the width and length of a ladder that can fit inside a window well without resting on the ground or floor of the window well. Some embodiments may comprise dimensions approximately 1-2 feet wide and between 2.5 to 10 feet tall or more, depending on the dimensions of the window well.
(60) In certain embodiments the main ladder support frame 602 may comprise any suitable material including plastic, composites, metal or any other suitable material or combination of materials. In certain embodiments plastic may present advantages to prevent icing. In other embodiments the base of the rails are curled around to create a support structure 624 which spaces the frame from the wall of a window well.
(61) In some embodiments the two rails of the stationary section 602 are a fixed distance apart and are connected by a spacer bar at the top of the frame and a fulcrum bar 618 at the bottom of the frame. The fulcrum bar 618 is set back from the rail.
(62) In some embodiments, a first support structure 625 may extend outwardly from the first side rail 622a and/or a second support structure 625 may extend outwardly from the second side rail 622b. In these and other embodiments, a first end of the fulcrum 618 may be coupled to the first support structure 624 and/or a second end of the fulcrum 618 may be coupled to the second support structure 624.
